HOT-WATER H EATER.

SPECIFICATION forming part of Letters Patent No. 492,695, dated February28, 1893.

Application filed June 20 1892.

To all whom it may concern.-

Be it known that I, HARVEY T. NYE, acitizen of the United States, and aresident of Cleveland, countyof Ouyahoga, State of Ohio, have inventedcertain new and useful Improvements in Hot-Tater Heaters, of which Ihereby declare the following to be a full, clear, and exact description,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in hot water sectional flue heatingapparatus and its objects are to provide the greatest amount ofheatingsurface with the minimum requirement of fuel, together with aformof construction which will insure equal expansion and contraction of allparts. I obtain these advantages by means of the combination andarrangement of parts anddetails of construction shown in theaccompanying drawings, described herein and more specifically pointedout in the claims.

In the accompanying drawings Figure 1 is a front elevation of thefurnace with the walls partially removed showing the arrangement offines. Fig. 2 is aside elevation of the same showing walls in verticalcentral section.

A in the drawings represents the inlet water p1pes.

B and B, are vertical supply pipes, connected on either 'side of theheater by the horizontal pipes O, O, which communicate with the header Dby means of the short vertical connections E.

- Cross headers F just above the fire-box in front of the heater andcross header G in the rear of the fire-box serve as lower supports for aseries of pipe bends H, and Iwhich completely fill the space between theside frames formed by the pipes B B, and O and enter the header D fromeitherside. It will be seen that there are two sets of bends, H and I;one set H entering the cross pipe Fabove the firebox and the othersetlentering the cross pipe G at the farther and lower end of thefire-box after forming its vertical rear wall as seen at I. A furtherset of pipe L on either side of the heater extends from the inlet pipe Ain diagonal bends to the header D, and thus with the vertical pipes Iinclose the fire-box upon three sides. A bridge wall M supports theSerial No, 437,530 (No model.)

inner extremities of the grate bars N and an ash pit O is formed belowthe heater.

In operation cold water is introduced from the mains or other convenientsource into the lower extremities of the pipes B B until the heater isfilled with water.

The header D is provided with any desired number of outlet nozzles dwhich communicate with pipes leading to radiators in con venient partsof the building containing the heater which are also filled with waterthe return pipes leading into the cross pipes or headers E and G asshown. It will be seen that when the whole system of pipes has beenfilled with water and heat applied to the fireening the longitudinalpipes all other portions especially the cast headers remaining the same,nor need the grates be changed.

I believe myself to be the first to employ this specific form of heaterfor water. i

What I claim as new, and desire to secure by Letters Patent, is

1. In a sectional heater, the combination of vertical inlet pipes B andB, forming the corner supports to theheater, transverse headers F and Gconnecting the vertical pipes across the heater, pipes 0 connecting thevertical pipes longitudinally, a transverse header D.

supported upon the pipes O by means of vertical sections E, and a doubleseries of pipe bends secured at their upper extremities to the header D,and at their lower extremities the one to the header F, and the otherterminating in vertical pipes forming the rear wall of the fire-box andsecured to the header G, substantially as and in the manner set forth.

2. In a water heater, of sectional pipe constructions a fire-boxprovided with vertical corner posts consisting of inlet pipes B and B,transverse header pipes F and G,in combination With a double system ofbent pipes communicating. with the said headers F and G and commonheader D, the lower portion of the system of pipes communicating withheader F being vertical and forming the rear Wall of fire-boxsubstantially as and for the purpose described.

3. In a sectional hot Water heater the combination of vertical cornerinlet pipes, B and B, transverse headers F and G and D and longitudinalpipes C connecting the inlet pipes, circulating pipe P connectingheaders F and G, circulating pipe bends connecting header D with headersF and G, the pipes connecting header D and headers F forming the rearWall of the fire-box, and auxiliary tially as described.
